VAE Powder is a white or off-white water-soluble liquid powder produced by spray-drying special water-based emulsion.
Mostly based on vinyl acetate and ethylene. It dissolves in water easily and quickly forms emulsion .It has high adhesion, water resistance, processability and heat insulation,.It is mainly used into the cement mortar as additive of building industrial.
The RDP powder replacementis product. a water soluble redispersible powder.It is a new kind of synthetic rubber powder. It is easily soluble in water and forms an emulsion quickly. Its chemical properties are identical to those of the original emulsion. It has good bond strength, excellent alkali resistance, weather resistance, freeze-thaw resistance and excellent flexibility at low temperatures.
VAE Re-Dispersible Polymer Powder(RDP) is produced by spray-drying special water-based emulsion, mostly based on vinyl acetate and acrylic acid, dissolves in water easily and quickly forms emulsion.
This VAE RDP Re-Dispersible Polymer Powder Used in construction mortar and wall putty. In the construction, the dosage of VAE is very low ,6-12kg per ton of mortar, but an important additive , mproving flexibility and its elastic in Mortar.
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
